PROBLEM TO BE SOLVED: To provide an auger type ice making machine strong against environmental fluctuation. SOLUTION: A cooling device 38 of this auger type ice making machine includes a vapor compression type primary circuit 40, and a secondary circuit 50 constituted by connecting a secondary heat exchange part 52 cooled by a heat exchanger HE by the primary circuit 40, and an evaporator EP positioned at a lower part of the heat exchanger HE in a contact state with a refrigerating casing 22, by refrigerant pipes 54, 56. The cooling device 38 is constituted to naturally circulate the refrigerant by temperature gradient of the secondary heat exchange part 52 cooled by the heat exchanger HE and the evaporator EP, and to cool the refrigerating casing 22 by the evaporator EP.
